Trinh Tham Nghiep Du (Amateur Detectives) is the only new TV series for children made by the HCM City Televison Studio (TFS) this year.
"We lack funds to make more serials," said Pham Truong Son, head of the HCM City Television's Film Selection Office.
"The money needed to make a TV serial for children is nearly double that for adults," Son said.
Several years ago, TFS made three or four serials.
Reruns of Giac Mo Bien (Dreams of Sea) and Gia Dinh Phep Thuat (A Witchcraft Family), produced by TFS three years ago, are being broadcast now.
